Question : The circumferences of the two circles are touching externally. The distance between their centres is 12 cm. The radius of one circle is 7 cm. Find the diameter (in cm) of the other circle.
Option 1: 12
Option 2: 10
Option 3: 8
Option 4: 5
Correct Answer: 10
Solution : When two circles touch each other externally, the distance between their centres is equal to the sum of their radii. ⇒ Distance = 12 = 7 + Radius of other circle ⇒ Radius of other circle = 12 – 7 = 5 cm So, the diameter of other circle = 2 × 5 = 10 cm Hence, the correct answer is 10.
Question : Yogita sold a plasma TV at a 20% gain to Shyamla, and Shyamla sold it to Deepa at a 10% profit. If Deepa had to pay Rs. 33,000 for the plasma TV, find the cost price of the plasma TV for Yogita.
